ere are several installation methods for wood flooring. _Attentions. What kind of wood lines does Cummo focus on? The basic situation of the wood line installation method is introduced. Roma elaborates several strategies of wave board installation through survey data. Baby spends a lot of time collecting and organizing the performance analysis of how to cut the cement board wood wire board. This content is for everyone to learn and understand.
What is the cement board?
It is an environmentally friendly green building material—ease of processing and durability of cement. Wood wool cement board began to be widely used in Europe in the 1940s, also has now become a widely used building material in the world.
It has broad practicability and excellent performance and has many advantages such as corrosion resistance, heat resistance, and corrosion resistance, easy processing, good compatibility with cement, lime, gypsum, and environmental protection.
What is the difference between the Meiyan cement board, the cement board, and how to cut the cement board?
Cement board is a kind of decoration material, which is as large as the gypsum board. The size is 1220X2440 (MM), the wood wool cement board is more delicate, and the beautiful rock is rougher. Clearwater slabs are exact water concrete slabs,
It belongs to one-time casting molding, without any external decoration, and directly uses the natural surface effect of cast-in-situ concrete as the finish, so it is different from ordinary concrete. The surface is flat and smooth; the color is uniform, the edges and corners are transparent.
There is no collision damage and pollution, but only on the surface; it is very natural and solemn to apply one or two layers of transparent protective agent. Fair-faced concrete is the most advanced form of expression in concrete materials, and it shows the essential aesthetic sense, embodying the taste of “plain facing the sky”.
How to cut cement board concrete has a simple, natural, and calm appearance. The inherent thickness and elegance are unmatched by some modern building materials. The softness, rigidity, warmth, and apathy of the material itself not only affects people’s senses and spirit but also expresses architectural emotions. Therefore, the architects believe that this is a noble and simple, seemingly simple, but actually more artistic than gold brilliant.
specification
Sheet moving and cutting.
Cutting fiber cement boards usually requires a chainsaw or a mechanical cutter. There are three ways to cut:
When cutting the board, pay attention to the wind direction, try to avoid the powder from inhaling into the body, wear a mask or special protective tools; the board powder entering the lungs for a long time may cause disease.
classification
At present, most domestic asbestos fibers are used for reinforcement. Also, This kind of fiber cement board is called chrysotile fiber cement slab; the other is asbestos-free fiber, using pulp and wood chips.
National industry standards:

Installation method
Therefore, water curing has two functions: one is to prevent cracking, and the other is to ensure that the cement is fully hydrated to complete the strength formation of the adhesive.
Of course, water spraying is a typical folk construction process. If it is a project, the daily Water dripping will be tiring, and it can not be accurately grasped.
What should we do?
Also, Special mortars will used; that is, different admixtures will add to the cement mortar so that the cement mortar has some other special functions.
In special mortars, if you want to solve the above problems, you need to add hydroxypropyl methylcellulose, which is called a water-retaining agent in the industry. After adding it, the drying time of the cement mortar is controlled, so there is no need to shower every day Water has been cured.
According to the difference in season and temperature, the full hardening of cement, that is, the curing molding period is generally 28 days in principle, but there are significant differences in the actual engineering. The specific curing period should be based on the combination of structure type, section size, concrete designation, cement type, etc.
Conditions
such as air temperature, humidity, evaporation, and curing technology are specifically determined, but the general 15-day curing intensity is generally sufficient in summer, and sometimes in winter, such as the pavement, sometimes the conditions are low, and it is difficult to achieve adequate intensity for two months. However, no matter what kind of curing diseases, the first 7 days must be ensured to cover the heat preservation and moisture conservation. For structures with severe curing conditions, warm Water, or even pressure, Water can be used for curing.
How to maintain the cement board?
Cement mortar plastering must remain watered to prevent cracking. It is scientific and must do.
However, Cement is a hydraulic material. It must pass through a good hydration process to achieve the desired strength of how to cut the cement board. After drying, the hydration process of the cement will end. In simple terms, if the hydration of cement takes 8 days to reach the ideal value, but it dries in 2 days, and the hydration process is terminated, its strength will be particularly loss. Therefore, timely watering every day is also to keep the cement hydration process continuing.
